Heating repair and service in Kenmore, WA
When the house will not warm up, our Redmond branch sends a heating technician to Kenmore to find out why and fix it. We service gas furnaces, electric furnaces, heat pumps, ductless mini-splits and dual-fuel systems. Call (425) 645-0404 or send the form to book.
Kenmore’s damp, cool winters mean heating runs for a large part of the year. Puget Sound Energy supplies both electricity and natural gas in the city (City of Kenmore, utility providers), so homes here heat with gas furnaces, electric furnaces and baseboards, heat pumps, or a combination.
What repairs usually cost
Seattle-area data puts most furnace repairs between $139 and $544, averaging about $341, with major repairs reaching about $2,000 (Angi, Seattle furnace repair costs, updated August 2026). These are published estimates, not our prices. You get a written price after diagnosis, and nothing is done without your approval.
Symptoms and likely causes
A guide to what we typically find behind the most common complaints:
| What you notice | Where we look first |
|---|---|
| No heat at all | Thermostat, power switch, breaker, door safety switch, ignitor |
| Burner lights, then goes out | Dirty flame sensor, pressure switch, blocked vent or condensate drain |
| Heat pump blows cool air for long periods | Low refrigerant from a leak, defrost fault, backup heat not engaging |
| Loud squeal, rattle or grinding | Blower bearings, belt, loose panels, inducer motor |
| Some rooms cold, others warm | Filter, closed or blocked registers, disconnected ducts, damper settings |
| Electric furnace runs but air is cool | Failed heating elements or sequencer |
If a carbon monoxide alarm sounds, leave the house and call 911, then PSE, before calling us.
Electric heat and PSE rebates
Plenty of Kenmore homes and townhomes heat with electric baseboards or an electric furnace. That is the most expensive way to heat with electricity, and it is where a heat pump pays back fastest. PSE pays $1,500 toward a heat pump that replaces electric resistance heat, plus up to $2,400 more for income-qualified households through Efficiency Boost (PSE electric resistance to heat pump rebate). Homes with a PSE gas furnace can add a heat pump for dual-fuel operation and apply for PSE’s hybrid rebate of $1,500, plus up to $2,400 (PSE hybrid heat pump rebate). See our Kenmore heat pump page.

Repair or replace?
We will tell you honestly when a repair makes more sense. Replacement is worth pricing when the equipment is 15 to 20 years old and needs a major part, when it has broken down in more than one recent winter, when a heat exchanger or venting defect is found, or when electric heat bills are high enough that a heat pump would pay for itself. Details on our Kenmore furnace replacement page.
Split levels and hillside homes
On the hills of Inglewood, Arrowhead and Kenlake Vista, many homes are split-level or have daylight basements. The lower floor often runs cold while the upper floor overheats, because warm air rises and the return is in the wrong place. Before recommending new equipment, we measure room temperatures and airflow. Fixes range from adjusting dampers and adding a return, to sealing and insulating ducts, to zoning with a second thermostat or adding a ductless head to the level that never keeps up.
Ductless heat for bonus rooms and additions
A room over the garage, a converted basement or a recent addition often never gets enough heat from the main system, because the ducts to it are long, small or missing. Extending ductwork can be disruptive and still leave the room behind. A single-zone ductless mini-split heats and cools just that space with its own control, needs only a small opening for the line set, and does not change the rest of the system. In a home heated by baseboards, a multi-zone ductless system can replace several heaters at once and qualify for the PSE electric heat rebate.
Damp air and heating
Near Lake Washington and the Sammamish River, winter air is damp. A heating system that short cycles leaves rooms feeling clammy, and a crawlspace with poor drainage raises indoor humidity. Properly sized equipment running longer, gentler cycles, a clean filter, and bath and kitchen fans that vent outdoors all help. If you see condensation on windows every morning or smell mustiness in lower rooms, tell the technician; we check airflow and ventilation along with the equipment.
Thermostats and settings
Some heating calls are solved at the wall. Dead batteries, a thermostat set to the wrong system type after a replacement, a smart thermostat installed without the common wire it needs, or a schedule that fights how the household lives can all look like equipment failures. With heat pumps, settings also decide the bill: large setbacks overnight can trigger the backup strips every morning. We check wiring and configuration, set schedules that suit your routine, and replace thermostats where it helps, including models that manage multi-stage and variable-speed equipment properly.
Inside a heating service call
Here is what to expect when our technician arrives in Kenmore. First, a conversation: when the problem started, what it sounds or smells like, and any codes the furnace is flashing. Next, measurement rather than guesswork: electrical readings, gas pressure on gas equipment, temperature rise across the furnace, and refrigerant pressures on heat pumps. Then, a written summary of what failed and your repair options, with replacement figures alongside if the system is near the end of its life. After the repair, the system runs a full heating cycle and gas appliances get a combustion and carbon monoxide check. If a part has to be ordered, you will know when it is due and how to keep warm until then.
Annual service
- Inspect and clean burners, ignitor and flame sensor on gas furnaces.
- Test safety switches and check the flue and piping. A tune-up is not a carbon monoxide test, so keep working CO alarms on every level.
- Clear the condensate trap and drain on high-efficiency furnaces.
- Check electric elements and sequencers on electric furnaces.
- On heat pumps, check refrigerant pressures, defrost cycle and backup heat.
- Check the blower and airflow, replace the filter, and verify thermostat settings.
Early fall is the best time, before the first cold, wet week.
Permits and safety
Installing or replacing gas or mechanical equipment in Kenmore requires a City of Kenmore permit (City of Kenmore, Do I Need a Permit?), and new wiring needs an L&I electrical permit (L&I, cities that do their own electrical permits). Like-for-like repairs do not. Every gas repair we do ends with a carbon monoxide check before we leave.
Warranty and Home Comfort Club
We support the manufacturer’s warranty on covered equipment parts, and we stand behind our heating installations with a 1-year labor warranty from installation.
Join our Home Comfort Club, a monthly membership starting at $15 a month, and a new system we install gets extended labor coverage for as long as your membership stays active, up to 5 years from installation. Ask your technician or comfort advisor for the current plan details.
Kenmore heating FAQ
How much does furnace repair cost in Kenmore?
Seattle-area data puts most furnace repairs between $139 and $544, about $341, with larger repairs up to about $2,000 (Angi, August 2026). We give a written price after diagnosis.
Is there a heat pump rebate in Kenmore?
Yes. PSE pays $1,500, plus up to $2,400 for income-qualified homes, to replace electric resistance heat with a heat pump, and $1,500 plus up to $2,400 to add a heat pump to a PSE gas furnace.
Why is my lower floor always cold?
Usually airflow: warm air rises and the return or supply layout favors the upper floor. Dampers, an added return or zoning often fix it.
Do I need a permit to replace a furnace in Kenmore?
Yes. The City of Kenmore issues the permit for gas and mechanical equipment, and L&I for any wiring. We handle both.
How often should my heating be serviced?
Once a year, ideally in early fall; heat pumps that also cool benefit from a spring visit.
Why does my heat pump turn on the backup strips every morning?
Usually a large overnight setback. A smaller setback or a thermostat with adaptive recovery keeps the strips off.
Do you repair electric furnaces?
Yes: heating elements, sequencers, relays and blower motors, and we can price a heat pump conversion if the furnace is near the end of its life.
What warranty comes with your work?
We support the manufacturer’s warranty on covered equipment parts, and our labor warranty covers installations for 1 year from installation. Home Comfort Club members (monthly membership starting at $15 a month) with a new system installed by Home Comfort Alliance get extended labor coverage for as long as their membership stays active, up to 5 years from installation.
